The project is aimed at designing a wind turbine for tapping the low speed wind in urban locations. It is to be noted that most of the high wind power density regions in the zone of high wind speed are already being tapped and this offers a large scope for the development of this low wind speed turbines. Our study focuses primarily on designing the blade for tapping power in the regions of low wind power density. The aerodynamic profiles of wind turbine blades have crucial influence on aerodynamic efficiency of wind turbine. This involves the selection of a suitable airfoil section for the proposed wind turbine blade. The NACA 63 series is chosen as the basic group for investigation because they have good low speed characteristics and the power curve is better in the low and medium wind speed ranges. In this paper NACA 63-415 airfoil profile is considered for analysis of wind turbine blade. NACA 63-415 airfoil profile is created by using the co-ordinate file generated in JavaFoil. A C-Mesh Domain for the fluid around the airfoil is created using Design Modeler in ANSYS Workbench. The CFD analysis is carried out using STAR-CCM+ at various angles of attack from 00 to 160 . The coefficient of lift and drag values are calculated for low Reynolds number and the pressure distributions are also plotted. The airfoil NACA 63-415 is analyzed based on computational fluid dynamics to identify its suitability for its application on wind turbine blades and good agreement is made between results.
